Description

General part information

MIC39151 Series

The MIC39150, MIC39151, and MIC39152 are 1.5A LDO voltage regulators that provide a low-voltage, high-current output with a minimum of external components. Utilizing proprietary Super βeta PNP® pass element, the MIC39150/1/2 offers extremely low dropout (typically 375mV at 1.5A) and low ground current (typically 17mA at 1.5A).

The MIC39150/1/2 are ideal for PC add-in cards that need to convert from 3.3V to 2.5V or 2.5V to 1.8V with a guaranteed maximum dropout voltage of 500mV over all operating conditions. The MIC39150/1/2 exhibit fast transient response for heavy switching applications and requires only 10µF of output capacitance to maintain stability and achieve fast transient response.

The MIC39150/1/2 is fully protected with current limiting, thermal shutdown, reverse battery protection/lead insertion, and reverse leakage protection. The MIC39151 offers a TTL logic-compatible enable pin and an error flag that indicates undervoltage and overcurrent conditions. Offered in fixed voltages of 2.5V, 1.8V, and 1.65V, the MIC39150/1 comes in the TO-220 and TO-263 (D²Pak) packages. The MIC39152 adjustable option allows programming the output voltage anywhere between 1.24V and 15.5V and comes in 5-Pin, TO-263 (D²Pak) and TO-252 (D-Pak) packages.
